It's not that interesting because there was a well known problem with 
NForce2 chipsets locking up under moderate IO.  This has been fixed in 
all recent kernels.  There was some fixup required in their IO-APIC 
hardware that could be worked around.  I'm running both 2.6.9 and 2.4.27 
on NForce2 hardware with great success.  Infact my mythbackend has 
regular uptimes over 30 days.

Try newer kernels, the ones that shipped originally with FC were 
susceptible to this problem.
